What is the effect of temperature and density on the movement of water?

Answers

Answer 1

Answer: temperature affects the movement of water because if the liquid is cold the molecules come together. Therefore, the water moves slower, and if the liquid is hot the molecules spread apart and move faster.

A 500 gram piece of metal has a volume of 2.75cm3 what is the density

Answers

Answer: $181.82\ g/cm^3$

Explanation:

Given that the volume of a piece of metal = $2.75\ cm^3$

Mass of piece of metal= 500 g

Formula to calculate the density is given by :-

$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

Then, the density of piece of metal is given by :-

$\text{Density of piece of metal}=(500)/(2.75)\n\n\Rightarrow\ \text{Density}=181.818181818\approx181.82\ g/cm^3$ [Rounded to the nearest two decimal places.]

Hence, its density of piece of metal= $181.82\ g/cm^3$

density is mass / volume so it is 500 / 2.75=181.82 g/cm3

John Dalton thought that atomsa. contain molecules.
b. cannot be broken down further.
c. are all composed of carbon.
d. have no mass.

Answers

Answer:

Explanation:

Atoms are those particles which cannot be broken down further. But, later on the subatomic particles were discovered

Final answer:

John Dalton's Atomic Theory states that atoms are indivisible and cannot be broken down further. They combine to form molecules and are not all composed of carbon. Atoms do have mass.

Explanation:

John Dalton, an English chemist, is famous for his theory of atomic structure, also known as Dalton's Atomic Theory. According to this theory, atoms are the tiniest particles of matter which cannot be divided or broken down further into simpler substances by chemical means. Thus, the correct answer to the question would be (b) - atoms cannot be broken down further.

Atoms can combine in various proportions to form molecules, but they themselves do not contain molecules. Also, not all atoms are composed of carbon, there are many other elements such as hydrogen, oxygen, nitrogen, to name a few. Finally, atoms do possess mass, it is one of their fundamental properties.

What is the difference between refraction and rarefaction?

Answers

The difference between light reflection and refraction is simple. In reflection, the light ray striking the plane returns to the originating source or medium as the waves spring off the surface. in refraction, the waves go through the surface and it alters their speed and direction.

what is reflection?

Reflection is the bouncing back of light when it strikes a smooth surface. Generally occurs on shinny surfaces that only allow rebounding of light without permitting penetration through it. In this process, light bounces back and returns back in the same direction.

Refraction is the bending of light rays when it travels from one medium to another. This occurs in transparent surfaces that allow bending of the ray to a different medium.

In this process, light changes path i.e travels from one medium to another.

What is the difference between refraction and rarefaction?

Refraction occurs when a wave crosses a boundary from one medium to another. A wave entering from an angle will change direction

Rarefraction refers to the "bending of wavelengths around an edge"of an object. diffraction depends on the size of the object relative to the wavelength of the waves.
